The paper discusses the design and development of the platen used in a special-purpose machine by ABC textile industry in Coimbatore. The objective is to attain uniform heat-setting temperature on both top and bottom platens of the machine. This research work is therefore important as it addresses the real need raised by the industry to have better heat-setting process in order to optimize and develop a better-quality end-product. Heat setting changed the structure and gave the fibers an unyielding property. Elongation of the fabric varies with different temperatures. Hence, it is very much essential to maintain precise and uniform temperature in heat setting. The author proposed design modifications on the heating element configuration and the material of the platen to achieve uniform temperature and improved heat transfer. Numerical validation and experimentation were carried out to ensure the design modifications and the attainment of uniform temperature with improved heat transfer in the top and bottom platen across different zones in the platen. The effect of changing the design on thermal characteristics, results and the benefits achieved by the company are discussed.
